PRINTERS RULE IN CORNER, STRAIGHT-STRIP, CURVED, OR TUBULAR FORM.

To all whom it may concern:

Be it known that I, WILLIAM C. F. PAPKE, a citizen of the United Statesof America, and a resident of Cincinnati, in the county of Hamilton andState of Ohio, have invented certain new and useful Improvements inPrinters Rules in Corner, Straight- Strip, Curved, or Tubular Form, ofwhich the following is a specification.

This invention relates to printers-rules and the object thereof is toprovide a metallic rule in either corner, straight-strip, curved, ortubular form, the bottom or base portion of which is continuous ineither a straight line or that of a single arc and the upper or printingportion of which takes the desired broken or irregular curved orangulated lines to suit the design that the rule is intended to print.

The full nature and consistency of the invention will be described indetail hereinafter and particularly pointed out in the claim.

In the accompanying sheet of drawings, Figure 1 is a perspective View ofa rulecorner embodying my invention herein; Fig. 2, a perspective viewof a straight piece of rule also embodying my invention; Fig. 8, alongitudinal, sectional elevation taken on the vertical dotted-line a,a, of Fig. 1, but showing in addition to the corner seen in Fig. 1, acontiguous straightstrip of rule such as that seen in Fig. 2; Fig. l, asectional plan taken on the dottedline Z), Z), of Fig. 3; Fig. 5, a planshowing a hollow-square or tubular form of printersrule also embodyingmy invention herein; and Fig. 6, a sectional elevation taken on the Iclotted-line c, c, of Fig. 5.

In these views, 1 indicates the base or body portion and 2 the upper orprinting portion of the rule. Both portions 1 and 2 are made integraland preferably of sheetmetal, usually brass, as customary in thecomposition of printers-rules. The base or body portion 1 in all formsof the rule is carried continuously straight throughout its length, orin one continuous arc throughout any curved form, but at corners thesaid straight base is bent at a right-angle, or at such another desiredangle as may be required in the printing job, the form seen in Fig. 1being that of a right-angled corner and the bend in the metal in suchcorner being continuous from top to bottom of the rule,

including both the base and printing portions thereof. It will be seenin Fig. 1, that the edge 3 of the angle is continuous or unbroken fromthe bottom of the body portion upward to the printing face of theprinting-portion 2 and thus a rigid contact is provided for thecorner-rule its full height in locking up the rules and type in theprinters-form.

The printinguoortion 2 in the respective forms seen in the several viewsof the drawing is of any desired waved, irregularlycurved, or angulatedline formation and each desired formation 4 is made in the metal bystriking-up or pressing inwardly, by means of dies or the like, theupper portion 2 of the metal strip to a vertical depth to suit theheight of the slugs or other like spacing or filling matter used in theprinters-form. But the bottom edge of each vertical depth orinwardly-pressed portion 4 of the metal is duly separated or cut away asshown at 5, from the body portion 2 of the strip at the several pointsto which the irregular portions of the lines of the printing-face aremade and presents a decided stop or shoulder at intervals along theprinting-portion of the rule to accommodate said slugs or other likespacing or filling thereunder.

It will be seen, (in Fig. 1 particularly,) that the apex of thecorner-rule shown is intact from top to bottom of the entire clevice andremains unbroken and continuous to provide for a proper locking up ofthe said corner-rule in the corner of the printers-form.

In Fig. 5 I have shown how my invention is adapted for use in makingtubular rule, of square cross-section, for use in ornamental printing.The irregular or broken line printing-portion construction is the sameas in the above-described corner and straightstrip forms, the verticaldepth or inwardlypressed portions 4 being cut away at 5 at their loweredges and forming slug stops necessary in completing the proper lockingand setting up of the printers-form.

It is obvious that many other forms and designs of printing-face may beprovided in the upper part 2 of the rule, whether in the wings ofcorners or along straight or irregular sides, the essential feature ofmy invention herein calling for an intact straight or continuous base orbody portion 1 and an integral printing-portion 2 having a series ofinwardly pressed or struck'up lateral portions 4 made therein atintervals to suit the design or character of line it is desired toprint. The actual corner or angle is not cut away or struck-up eitherinwardly or outwardly, but the base and printing portions remain intactand in a continuous perpendicular line from top to bottom of the saidactual corner as aforesaid. The cut-away portions 4 begin at either sidesaid actual corner or angle and the latter is thus more readily made inthe sheet-metal strip with a clean and definite Vertical edge that isvery ifmportant in the locking-up of the printersorm.

I claim:

Printers-rule comprising an angulated corner having a plane base or bodyportion, integral, irregularly curved or angulated printing-wingportions or extensions pressed or struck-up inwardly away from said baseto suit the desired design and form slug stops and a perpendicularlyunbroken or continuous corner comprehending said base and printingportions ofthe rule.
